Ez-muur Patented July 15, 1930 LAWREN E- 1).: BEIMBoLT, or C EVE AN OHIO, AssrGNon r'o UNIVERSAL AU'ro o- BILE-FOBWA RDENG COM RANY; A CORPORATION OF MICHIGAN onrrro GOVERNOR Application filedseptember 21; 1929'. Serial No; 394,192.

This inventionrelates to-internal combustion engines, and more particularly to means for governing the maximum amount of com bustible mixture which may be drawn into the'cylinders of'an engine of this type.

*One object of this invention is to provide a governor which has no 'moving'parts, which :may be readily fixed in position and eii'ectively sealed, and which may be manufactured at a minimum cost.

A further object is to provide a governor of this type which may be attached to a standard manifold and carburetor assembly of an automobile engine without alteration there- 1 in to limit the speed at which the car may be driven and prevent excessive racing of the engine when the car is in neutral, and which may be readily removed after it has served its purpose.

It has become customary to deliver new automobiles by driving them from the factory or assembly plant to their destination. It has frequently occurred, however, that the drivers employed for such delivery work have driven the cars at a higher rate of speed than is proper for a new car, resulting in burned out or loosened bearings, scored cylinders, or other injuries, which greatly lesson the life and value of the car. The governor which forms the subject-matter of this application is of such a nature that it may be attached to an automobile and sealed before the same is turned over to the driver, so that delivery of the automobile with the seal 3 intact will be tangible evidence to the purchaser that it has not been abused.

In the drawings, which illustrate one embodiment of the invention;

Fig. 1 is a diagrammatic elevational view of the carburetor side of an internal combustion engine showing my improved governor in position between the companion flanges of the carburetor and the intake manifold; Fig. 2 is a section taken on the line 22 of Fig. 1;

Fig. 3 is a section through the intake riser, taken on the plane indicated by the line 3-3 to of Fig. 2;

Fig. 4 is a plan view of the governor detached from the engine; and

Fig. 5 is a section taken-on the line 5-5 of Fig. 3.

Referringto the drawings wherein'like symbols designate corresponding parts throughout the several'views, theinternal combustion engine 1 is provided wit-h an'in-' take manifold 2 and a carburetor 3 joined together by means of companion flanges'a and 5 on a depending'porlion otthemanifold and an upstanding portion of the carburetor, respectively. Oppositely disposed bolts 7, 7, passing through registering; apertures in laterally extended portions of the flanges, ,5, normally secure thefianges together with-a gasket 6 interposed therebetween.

My" improved governor: consists of a plate member '9 adapted :tobe clamped between the flanges 4 and 5 and having a rectangular porw tion" 10 of'awidth to'fitclosely between the bolts 7, and two laterally extending arms 11 a'rrangedto abut the b-oltstoposition the plate. The plate is provided witha central aperture 8" positionedin such amanneras to be disposed in the intake passage and of-such a size'as to limit the flow offuel totheintake manifold to a pro-determinedquantity. The plate is provided with small apertures 12 near opposite edges thereof to receive a sealing wire 13, which'ispassedover bothv of the flanges 4 and 5 and fastenedwith a lead seal 14, as shownin Figure 5.

lVhen it is desired to use the governor, the bolts 7 are loosened slightly and the rectair gular p'ortionlO is placed between the flanges with the gasket on one side, and is pushed inwardly-between the bolts 7-untilth'ear1ns 11 contact with the bolts; The" latter are then tightenedrdown with suthcient force to efiect a seal-betweenthevariousparts; The plate is preferably; made of-relatively soft material, so that it' will readily conformto the surface of the flanges and'seal thejoint. The. wire 13 is then passed aboutthefia-nges and sealed by means of the lead seal let. When the purchaser or dealer receives the car, the device may be'quickly removed'by cutting the wire,--loosening the 1 bolts, and slipping; the plate-from 'itsposition: The

ion

original gasket 6 remains uninjured, and the car is restored to its original condition by simpl tightening the bolts.

Althou h one embodiment of the invention has been ascribed in detail, it is to be understood that the specific terminology employed is not intended to be restrictive, and that modification of the device disclosed can be made within the spirit and scope of the appended claims. i

I claim: I

1. In an internal combustion engine, a pair of fuel sup 1y pipes joined together by means of mating auges having bolts passing therethrough, and a governor consisting of an apertured late arranged to be interposed between said flanges and to fit between and in contact with said bolts in such a manner as to be restrained from movement intwo directions by the contact with said bolts, and tube freely removable in a third direction in the. lane of said plate without removal of any its.

2. In an internal combustion engine, a pair of fuel supply pipes joined together by means of mating flanges having bolts passing therethrough, and a governor consisting of an apertured plate arranged to be interposed between said flanges and to fit between and in contactwith said bolts in such a manner as to be restrained from movement in three directions by the contact with said bolts, and to be freely removable in a fourth direction in the plane of said plate without removal of any bolts. i p

3. In an internal combustion engine including a pair of fuel supply pipes having companion flanges at the meeting ends thereof, each of said flanges having a pair of oppositely disposed apertured extensions, and. a pair of bolts passing through the correspondmg apertures of said extensions, a governor for said engine comprising an apertured plate arranged so that, in assembling, it may be slipped between and in contact with said bo ts, and between said flanges without re moving any bolts.

4. In an internal combustion engine including a pair of fuel supply pipes having companion flanges atthe meeting ends thereof, each of said flanges having a pair of oppositely disposed apertured extensions, and a pair of bolts passing through the correspondmg apertures of saidextensions, a governor forsaid engine comprising an apertured plate having lateral arms ontwo sides thereof, and arranged so that, in assembling, it may be slipped in between said flanges and between and in contact with said bolts, without removing any bolts, andmay be positioned with said arms in contact with said bolts.

5. In an internal combustion engine including a pair of fuel supply pipes having com: panion flanges at the meeting ends thereof, each of saidflangies having a pair of oppositely disposed apertured extensions, and a pair of bolts passing through the corresponding apertures of said extensions, a governor for said engine comprising an a ertured plate arranged to be interposed etween said flanges, said plate having a portion provided with parallel edges adapted, in assembling, to be slipped between and in contact with said bolts without removing an bolts and having a pair of oppositely exten ing wing portions having edges substantially perpendicular to said arallel edges ada ted to contact with said olts to posit-ion said plate.

6. In an internal combustion engine, a governor comprising a plate member adapted to be positioned between the companion flanges on the carburetor and intake manifold of such an engine, and having a rectangular portion adapted, in assembling, to be slip d between the olts joining such flanges Wit iout removing any bolts, and a pair of oppositely extending wlng portions adapted to contact with such bolts.

In testimony whereof I hereunto aflix my signature this 14th day of September, 1929.
